Definitions
- the invention relates to wireless mobile communication devices and, more particularly, to wireless mobile communication devices arranged to support communications within a group of users.
- FIGURE 1 illustrates a conventional wireless communication system including a public switched telephone network 11 which communicates with a mobile services switching center 13.
- the mobile services switching center 13 also communicates with a home location register (HLR) 15 and a plurality of base stations at 17.
- the base stations 17 communicate with mobile communication devices 19 via the air interface
- FIGURE 2 illustrates a conventional arrangement wherein a group of wireless mobile communication devices 19 communicate with one another over various channels at 21.
- the channels at 21 represent the communication channels provided by the system of FIGURE 1.
- the mobile communication devices at 19 also communicate with one or more stationary devices at 23 via the channels 21.
- Example FIGURE 10 illustrates a conventional arrangement similar to FIGURE 2, including a plurality of mobile communication devices 19 communicating among themselves and with the home location register 15 via various channels 21.
- the channels at 21 are typically implemented using any of the following conventional examples: Short Message Service (SMS); General Packet Radio Service (GPRS); Unstructured Supplementary Service Data (USSD); and Cellular Digital Packet Data (CDPD).
- SMS Short Message Service
- GPRS General Packet Radio Service
- USSD Unstructured Supplementary Service Data
- CDPD Cellular Digital Packet Data
- the communication device 19 conventionally includes a memory having stored therein a listing of phone numbers of other group members. This permits the user to retrieve from the memory the phone number of another member of the group. Thus, one group member can call another group member at any time without memorizing the phone number of the other group member.
- a first group member wishes to check the status of a second group member, for example, to determine whether or not the second group member is busy
- conventional arrangements require the first group member to manually enter the phone number of the second group member and contact him via a conventional wireless communication session such as a telephone call. That is, there is no way for the first group member to know the status of the second group member without manually entering the phone number of the second group member and establishing a wireless communication session with the second group member.
- conventional arrangements require the first group member to contact each and every group member individually in the above-described manner in order to check the status of all members of the group. It is therefore desirable to provide a wireless mobile communication device arranged to permit a first member of a group to automatically monitor the status of another member of the group without manually establishing a wireless communication session with the other group member.
- the present invention permits a group member to automatically monitor the status of any other group member without manually establishing a wireless communication session with the other group member.

- FIGURE 3 illustrates only those portions of the wireless mobile communication device 31 necessary to understand the present invention.
- Various other well-known conventional portions of the wireless mobile communication device are omitted from FIGURE 3 for clarity of exposition.
- the communication device 31 of FIGURE 3 includes group update control logic 33 which receives various status inputs, including a group select input, and an input from a Global Positioning System (GPS) receiver 37 that provides precise geographic location information for the device 31.
- GPS Global Positioning System
- the group update control section 31 communicates bidirectionally at 38 with a group list section 35 (for example, a memory) and also communicates bidirectionally at 39 with other wireless mobile communication devices, for example, the wireless mobile communication devices used by other members of a group.
- the group update control section 33 can communicate bidirectionally at 39 with a home location register HLR.
- the contents of group list 35 determine which other devices can monitor device 31 and be monitored by device 31.
- the communication path 38 permits the status of other group members to be communicated to the group list, and to the user via audio and/or visual channels.
- Example FIGURES 4-7 illustrate diagrammatically various communications between wireless mobile communication devices according to the present invention.
- the wireless mobile communication devices are wireless mobile telephones having the features of FIGURE 3.
- phone A sends, via communication path 39 of FIGURE 3 and conventional communication channels such as shown at 21 in FIGURE 2, a
- the PING message includes the present status of phone A, for example, whether phone A is busy, idle, etc.
- the PING message also includes the identity of phone A, for example, the phone number, name of user, etc.
- every other phone in the group automatically updates its group list 35 to reflect the phone A status just received, and automatically responds to phone A with a PONG message which includes the status and identification of that particular phone.
- the PING message of FIGURE 4 can be broadcast or multicast to all group members' phones, or phone A can send an individual PING message to each of the other phones.
- Example FIGURE 5 illustrates phone A sending a PONG message to all other phones in the group.
- the PONG message includes the status of phone A and the identification of phone A as does the PING message of FIGURE 4.
- the PING message requires the other phones in the group to send a PONG message in reply to phone A
- the PONG message of FIGURE 5 does not require a reply from the other phones of the group.
- the other phones automatically update their group lists to reflect the phone A status just received.
- Example FIGURE 6 is similar to FIGURE 4, except phone A sends a PING message to phone B only. Phone B then automatically updates its group list and responds to phone A with a PONG message.
- Example FIGURE 7 is similar to FIGURE 5, except phone A sends a PONG message to phone B only.
- Example FIGURE 8 shows communication output control which is implemented in the group update control section 33 of the wireless mobile communication device 31 of FIGURE 3.
- the output control 81 first determines at 83 whether or not the communication device has been switched on. This is determined from one of the status inputs in FIGURE 3. If the device 31 has not been switched on at 83, then the output control determines at 85 whether or not the user is manually requesting that a message be sent. If not, then control returns to the decision block at 83. If the user is manually requesting that a message be sent, then either a PING or PONG message (see FIGURES 4-7) is output at 87 according to which has been manually selected. Thereafter, control returns to the decision block at 83.
- the group update control 33 automatically outputs at 89 a PING message to all other communication devices in the group (see FIGURE 4). Thereafter, the output control 81 examines the FIGURE 3 status inputs to determine at 82 whether or not a status change has occurred in the communication device.
- the FIGURE 3 status inputs that are monitored at 82 include, for example, the device's on/off switch, an input indicative of whether the user is dialing a phone number, or the location of the mobile unit from GPS receiver 37 (or cell identification in a cellular system). If a status change is detected, then the group update control section 33 automatically sends a PONG message to all other devices in the group at 84 (see FIGURE 5). Thereafter, the output control determines at 86 whether or not the state change at 82 was the mobile communication device being switched off. If so, then control returns to decision block 83.
- the output control determines at 88 whether a predetermined condition exists to trigger a selective PING message to a subset of the other communication devices in the group. It should also be noted that the output control proceeds to the determination at 88 immediately from decision 82 if there is no status change at 82. If it is determined at 88 that a selective PING (or PONG) message(s) is triggered, then the group update control 33 automatically outputs at 80 the selective PING (or PONG) message(s) to the appropriate communication device(s) in the group.
- An example of the aforementioned trigger condition is when no PING or PONG message has been received from a given device for more than a threshold time period.
- the output control determines at 91 whether or not the user is manually requesting that a message be sent. If not, then control returns to the decision block at 82. If so, then the PING or PONG message or messages are sent as desired at 92, and thereafter control returns to decision block 82.
- Example FIGURE 9 illustrates input service implemented by the group update control section 33 of the communication device 31 in FIGURE 3.
- the input service 90 first determines at 93 whether or not a PING message has been received. Control does not proceed until a PING message has been received. If a PING message is received at 93, then the group update control section automatically updates the group list at 95 to include the status received in the PING message, and automatically outputs at 97 a PONG message to the device from which the PING message was received.
- Example FIGURE 11 is a block diagram of a home location register (HLR) database according to the present invention. Various well-known conventional features of HLR are omitted from FIGURE 11 for clarity of exposition.
- HLR home location register
- the home location register data base of FIGURE 11 includes subscriber information and information about the location of the various mobile communications units.
- the home location register data base of FIGURE 11 includes mobile unit group membership information and group member status information.
- FIGURE 12 illustrates phone A sending a "check phone B status" message to the HLR.
- HLR automatically sends a message to phone A including the status and identification of phone B.
- Phone B then automatically updates group list 35 accordingly.
- FIGURE 13 illustrates phone A sending a "status update" message to HLR.
- the status update message includes the status of phone A and the identification of phone A.
- Example FIGURE 14 is similar to FIGURE 13 in that phone A sends a "status update” message to HLR including the status of phone A and the phone A identification information. However, FIGURE 14 also illustrates that HLR automatically forwards this "status update” message to other phones in the group such as phone B and phone C. These other phones then automatically update their group lists 35 accordingly.
- the "status update” message of FIGURE 14 will preferably include an identification of which group is selected to receive status updates, particularly if phone A is a member of more than one group.
- Example FIGURE 15 illustrates output control implemented by the group update control section 33 of FIGURE 3 when the communication sequences of FIGURES 12-14 are used.
- the output control 150 first determines at 151 whether or not the mobile communication unit has been switched on. If not, then it is determined at 153 whether or not the user is manually requesting a status update. If so, then the group update control section 33 can initiate a "check status" message (FIGURE 12) or a "status update” message (FIGURE 13), depending on which type of message has been manually selected.
- the mobile communication unit will either request a status update from HLR (see FIGURE 12) or will send a status update to HLR (see FIGURES 13 and 14).
- the unit will automatically send a status update message (see FIGURES 13 and 14) to HLR at 152.
- the input control monitors the status inputs of FIGURE 3 to determine whether or not any of the monitored status inputs have changed. If so, then a status update message is automatically sent to HLR (see FIGURES 13 and 14) at 156.
- the output control determines at 157 whether or not the status change at 154 was the mobile unit being switched off. If so, then control returns to the decision block at 151. If not, then control proceeds to the decision block at 158, which is also the point to which control proceeds from 154 if there is no status change at 154.
- the output control checks the trigger(s) to determine whether the group update control section should check the status of one or more of the other units in the group (see FIGURE 12).
- An example trigger is when no status update of a given unit has been received for a threshold period of time. If a trigger is active at 158, then the "check status" message is issued at 159. Thereafter, control proceeds to the decision block at 160, which is also the point to which control flows from 158 if there is no active trigger at 158. It is determined at 160 whether or not the user is manually requesting a status update. If so, then status is either retrieved from HLR (see FIGURE 12) or updated to HLR (see FIGURES 12 and 13) at 161. Thereafter, control proceeds back to decision block 154, which is also the point to which control proceeds from 160 if no manual request is detected at 160. Workers in the art will recognize that the group update control section
- FIGURES 3-9 and 12-15 can be readily implemented in hardware or software, for example, within the data processing section of a conventional wireless mobile communication device.
- Example FIGURE 16 illustrates at 162 the informational service provided by HLR according to the present invention.
- HLR determines whether a "check status" message (see FIGURE 12) has been received from a mobile unit in the group. If so, then HLR provides the requested status (see FIGURE 12) at 164. Thereafter, control proceeds to decision block 165, which is also the point to which control proceeds from 163 if no "check status" message is received at 163. It is determined at 165 whether or not a "status update” message is received (see FIGURES 13 and 14). If so, then HLR at 166 appropriately updates the status in its database (see group member status information section 111 in FIGURE 11) and at 167 forwards the received status to the other members of the group (see FIGURE 14).
- the portions 111 and 113 of the HLR data base in FIGURE 11 can be implemented as one or more lists that correspond to respective groups of users. Each entry of each list corresponds to a member of that group and contains, for example, the member's name, the unit's phone (or other identification) number, and the current status of the unit. Each list thus contains the pertinent information for all units/users in that group. Any desired group can be monitored by selecting the corresponding list in HLR.
- a conventional Visiting Location Register may also be modified to include portions 111 and 113 according to the invention.
- the modified VLR would then be capable of performing the operations described above with respect to HLR.
- the group list section 35 of the FIGURE 3 wireless mobile communication device 31 can contain, for each group to which the device belongs, a corresponding group membership list.
- the communication of FIGURES 4-7 can alternatively be supported by implementing the group list section 35 as a general phone book listing, wherein each entry in the listing can be tagged as appropriate with one or more group memberships (and corresponding status).
- the group list section would also include a second list of all groups that are represented by the tagged entries in the general phone book listing, each entry in this second list corresponding to a group. A particular group can then be selected for monitoring by simply selecting the corresponding entry from the second list.
- the group select input of FIGURE 3 is a user input that selects which group is to be monitored. Moreover, the group select input can designate the selected group as a closed user group so that the device 31 , while the closed user group designation is active, communicates to and receives communication from only the group members in the selected group.
- FIGURE 17 illustrates pictorially a wireless mobile communication device 170 according to the present invention.
- the user can dial another unit manually or check the status of another unit manually by using the arrow keys in the keyboard to select the position on the display that corresponds to the desired unit.
- a group can define its own status characters for use in the display.
- the group update control section 33 and the group list section 35 of FIGURE 3 can be implemented within the unit 170 shown in FIGURE 17, or can alternatively be implemented in a device connected to the unit 170, for example the personal digital assistant PDA shown in broken lines in FIGURE 17. Also, as an alternative to the display shown in FIGURE 17, the status information can be presented using audible signals such as, for example, synthetic speech. The audible signals could be provided via a speaker 173 or an earphone.
- Both of the aforementioned visible and audible status indications can be updated automatically whenever group list 35 is updated (see Figure 3).

Description
WIRELESS MOBILE COMMUNICATION DEVICES FOR GROUP USE
FIELD OF THE INVENTION
The invention relates to wireless mobile communication devices and, more particularly, to wireless mobile communication devices arranged to support communications within a group of users.
BACKGROUND OF THE INVENTION
FIGURE 1 illustrates a conventional wireless communication system including a public switched telephone network 11 which communicates with a mobile services switching center 13. The mobile services switching center 13 also communicates with a home location register (HLR) 15 and a plurality of base stations at 17. The base stations 17 communicate with mobile communication devices 19 via the air interface
18.
FIGURE 2 illustrates a conventional arrangement wherein a group of wireless mobile communication devices 19 communicate with one another over various channels at 21. The channels at 21 represent the communication channels provided by the system of FIGURE 1. The mobile communication devices at 19 also communicate with one or more stationary devices at 23 via the channels 21.
One conventional example of a stationary device at 23 is the home location register 15 of FIGURE 1. Example FIGURE 10 illustrates a conventional arrangement similar to FIGURE 2, including a plurality of mobile communication devices 19 communicating among themselves and with the home location register 15 via various channels 21.
The channels at 21 are typically implemented using any of the following conventional examples: Short Message Service (SMS); General Packet Radio Service (GPRS); Unstructured Supplementary Service Data (USSD); and Cellular Digital Packet Data (CDPD).
It is very common today for a group of persons to utilize respective wireless mobile communication devices 19, for example wireless telephones, to communicate with one another in order to accomplish a certain task. For example, teams of security
personnel, transportation crews, and arrangers of various other events often utilize a plurality of wireless mobile communication devices for communication with one another during performance of their assigned tasks. The communication device 19 conventionally includes a memory having stored therein a listing of phone numbers of other group members. This permits the user to retrieve from the memory the phone number of another member of the group. Thus, one group member can call another group member at any time without memorizing the phone number of the other group member.
If a first group member wishes to check the status of a second group member, for example, to determine whether or not the second group member is busy, conventional arrangements require the first group member to manually enter the phone number of the second group member and contact him via a conventional wireless communication session such as a telephone call. That is, there is no way for the first group member to know the status of the second group member without manually entering the phone number of the second group member and establishing a wireless communication session with the second group member. Moreover, conventional arrangements require the first group member to contact each and every group member individually in the above-described manner in order to check the status of all members of the group. It is therefore desirable to provide a wireless mobile communication device arranged to permit a first member of a group to automatically monitor the status of another member of the group without manually establishing a wireless communication session with the other group member.
The present invention permits a group member to automatically monitor the status of any other group member without manually establishing a wireless communication session with the other group member.

DETAILED DESCRIPTION
Example FIGURE 3 illustrates diagrammatically a wireless mobile communication device 31 according to the present invention. FIGURE 3 illustrates only those portions of the wireless mobile communication device 31 necessary to understand the present invention. Various other well-known conventional portions of the wireless mobile communication device are omitted from FIGURE 3 for clarity of exposition. The communication device 31 of FIGURE 3 includes group update control logic 33 which receives various status inputs, including a group select input, and an input from a Global Positioning System (GPS) receiver 37 that provides precise geographic location information for the device 31. These status inputs are described in more detail below. The group update control section 31 communicates bidirectionally at 38 with a group list section 35 (for example, a memory) and also communicates bidirectionally at 39 with other wireless mobile communication devices, for example, the wireless mobile communication devices used by other members of a group. Alternatively or in addition to bidirectional communication with other wireless mobile communication devices, the group update control section 33 can communicate bidirectionally at 39 with a home location register HLR. The contents of group list 35 determine which other devices can monitor device 31 and be monitored by device 31. The communication path 38 permits the status of other group members to be communicated to the group list, and to the user via audio and/or visual channels. Example FIGURES 4-7 illustrate diagrammatically various communications between wireless mobile communication devices according to the present invention. In the examples of FIGURES 4-7, the wireless mobile communication devices are wireless mobile telephones having the features of FIGURE 3.
In example FIGURE 4, phone A sends, via communication path 39 of FIGURE 3 and conventional communication channels such as shown at 21 in FIGURE 2, a
PING message to all other phones in the group. The PING message includes the
present status of phone A, for example, whether phone A is busy, idle, etc. The PING message also includes the identity of phone A, for example, the phone number, name of user, etc. In response to the PING message from phone A, every other phone in the group automatically updates its group list 35 to reflect the phone A status just received, and automatically responds to phone A with a PONG message which includes the status and identification of that particular phone. The PING message of FIGURE 4 can be broadcast or multicast to all group members' phones, or phone A can send an individual PING message to each of the other phones.
Example FIGURE 5 illustrates phone A sending a PONG message to all other phones in the group. The PONG message includes the status of phone A and the identification of phone A as does the PING message of FIGURE 4. However, whereas the PING message requires the other phones in the group to send a PONG message in reply to phone A, the PONG message of FIGURE 5 does not require a reply from the other phones of the group. The other phones automatically update their group lists to reflect the phone A status just received.
Example FIGURE 6 is similar to FIGURE 4, except phone A sends a PING message to phone B only. Phone B then automatically updates its group list and responds to phone A with a PONG message.
Example FIGURE 7 is similar to FIGURE 5, except phone A sends a PONG message to phone B only.
Example FIGURE 8 shows communication output control which is implemented in the group update control section 33 of the wireless mobile communication device 31 of FIGURE 3. The output control 81 first determines at 83 whether or not the communication device has been switched on. This is determined from one of the status inputs in FIGURE 3. If the device 31 has not been switched on at 83, then the output control determines at 85 whether or not the user is manually requesting that a message be sent. If not, then control returns to the decision block at 83. If the user is manually requesting that a message be sent, then either a PING or PONG message (see FIGURES 4-7) is output at 87 according to which has been manually selected. Thereafter, control returns to the decision block at 83.
If the device has been switched on at 83, then the group update control 33 automatically outputs at 89 a PING message to all other communication devices in the
group (see FIGURE 4). Thereafter, the output control 81 examines the FIGURE 3 status inputs to determine at 82 whether or not a status change has occurred in the communication device. The FIGURE 3 status inputs that are monitored at 82 include, for example, the device's on/off switch, an input indicative of whether the user is dialing a phone number, or the location of the mobile unit from GPS receiver 37 (or cell identification in a cellular system). If a status change is detected, then the group update control section 33 automatically sends a PONG message to all other devices in the group at 84 (see FIGURE 5). Thereafter, the output control determines at 86 whether or not the state change at 82 was the mobile communication device being switched off. If so, then control returns to decision block 83.
If it is determined at 86 that the device is not switched off, then the output control determines at 88 whether a predetermined condition exists to trigger a selective PING message to a subset of the other communication devices in the group. It should also be noted that the output control proceeds to the determination at 88 immediately from decision 82 if there is no status change at 82. If it is determined at 88 that a selective PING (or PONG) message(s) is triggered, then the group update control 33 automatically outputs at 80 the selective PING (or PONG) message(s) to the appropriate communication device(s) in the group. An example of the aforementioned trigger condition is when no PING or PONG message has been received from a given device for more than a threshold time period.
After the selective PING (or PONG) messages are output, or if the trigger is not active at 88, then the output control determines at 91 whether or not the user is manually requesting that a message be sent. If not, then control returns to the decision block at 82. If so, then the PING or PONG message or messages are sent as desired at 92, and thereafter control returns to decision block 82.
Example FIGURE 9 illustrates input service implemented by the group update control section 33 of the communication device 31 in FIGURE 3. The input service 90 first determines at 93 whether or not a PING message has been received. Control does not proceed until a PING message has been received. If a PING message is received at 93, then the group update control section automatically updates the group list at 95 to include the status received in the PING message, and automatically outputs at 97 a PONG message to the device from which the PING message was received.
Example FIGURE 11 is a block diagram of a home location register (HLR) database according to the present invention. Various well-known conventional features of HLR are omitted from FIGURE 11 for clarity of exposition. As is conventional, the home location register data base of FIGURE 11 includes subscriber information and information about the location of the various mobile communications units. In addition, the home location register data base of FIGURE 11 includes mobile unit group membership information and group member status information. These additional features according to the present invention enable the exemplary communications illustrated in FIGURES 12-14. As in FIGURES 4-7 above, FIGURES 12-14 illustrate wireless mobile telephones having the general features of
FIGURE 3.
In particular, FIGURE 12 illustrates phone A sending a "check phone B status" message to the HLR. In response, HLR automatically sends a message to phone A including the status and identification of phone B. Phone B then automatically updates group list 35 accordingly.
FIGURE 13 illustrates phone A sending a "status update" message to HLR. The status update message includes the status of phone A and the identification of phone A.
Example FIGURE 14 is similar to FIGURE 13 in that phone A sends a "status update" message to HLR including the status of phone A and the phone A identification information. However, FIGURE 14 also illustrates that HLR automatically forwards this "status update" message to other phones in the group such as phone B and phone C. These other phones then automatically update their group lists 35 accordingly. The "status update" message of FIGURE 14 will preferably include an identification of which group is selected to receive status updates, particularly if phone A is a member of more than one group.
Example FIGURE 15 illustrates output control implemented by the group update control section 33 of FIGURE 3 when the communication sequences of FIGURES 12-14 are used. The output control 150 first determines at 151 whether or not the mobile communication unit has been switched on. If not, then it is determined at 153 whether or not the user is manually requesting a status update. If so, then the group update control section 33 can initiate a "check status" message (FIGURE 12)
or a "status update" message (FIGURE 13), depending on which type of message has been manually selected. Thus, at 155, the mobile communication unit will either request a status update from HLR (see FIGURE 12) or will send a status update to HLR (see FIGURES 13 and 14). If the mobile communication unit is switched on at 151, then the unit will automatically send a status update message (see FIGURES 13 and 14) to HLR at 152. Thereafter, at 154, the input control monitors the status inputs of FIGURE 3 to determine whether or not any of the monitored status inputs have changed. If so, then a status update message is automatically sent to HLR (see FIGURES 13 and 14) at 156. Thereafter, the output control determines at 157 whether or not the status change at 154 was the mobile unit being switched off. If so, then control returns to the decision block at 151. If not, then control proceeds to the decision block at 158, which is also the point to which control proceeds from 154 if there is no status change at 154.
At 158, the output control checks the trigger(s) to determine whether the group update control section should check the status of one or more of the other units in the group (see FIGURE 12). An example trigger is when no status update of a given unit has been received for a threshold period of time. If a trigger is active at 158, then the "check status" message is issued at 159. Thereafter, control proceeds to the decision block at 160, which is also the point to which control flows from 158 if there is no active trigger at 158. It is determined at 160 whether or not the user is manually requesting a status update. If so, then status is either retrieved from HLR (see FIGURE 12) or updated to HLR (see FIGURES 12 and 13) at 161. Thereafter, control proceeds back to decision block 154, which is also the point to which control proceeds from 160 if no manual request is detected at 160. Workers in the art will recognize that the group update control section
33 described with respect to FIGURES 3-9 and 12-15 can be readily implemented in hardware or software, for example, within the data processing section of a conventional wireless mobile communication device.
Example FIGURE 16 illustrates at 162 the informational service provided by HLR according to the present invention. At 163, HLR determines whether a "check status" message (see FIGURE 12) has been received from a mobile unit in the group. If so, then HLR provides the requested status (see FIGURE 12) at 164. Thereafter,
control proceeds to decision block 165, which is also the point to which control proceeds from 163 if no "check status" message is received at 163. It is determined at 165 whether or not a "status update" message is received (see FIGURES 13 and 14). If so, then HLR at 166 appropriately updates the status in its database (see group member status information section 111 in FIGURE 11) and at 167 forwards the received status to the other members of the group (see FIGURE 14).
The portions 111 and 113 of the HLR data base in FIGURE 11 can be implemented as one or more lists that correspond to respective groups of users. Each entry of each list corresponds to a member of that group and contains, for example, the member's name, the unit's phone (or other identification) number, and the current status of the unit. Each list thus contains the pertinent information for all units/users in that group. Any desired group can be monitored by selecting the corresponding list in HLR.
A conventional Visiting Location Register (VLR) may also be modified to include portions 111 and 113 according to the invention. The modified VLR would then be capable of performing the operations described above with respect to HLR.
Considering again the examples of FIGURES 4-7 wherein the wireless mobile communication devices exchange status information directly with one another, in this environment the group list section 35 of the FIGURE 3 wireless mobile communication device 31 can contain, for each group to which the device belongs, a corresponding group membership list. The communication of FIGURES 4-7 can alternatively be supported by implementing the group list section 35 as a general phone book listing, wherein each entry in the listing can be tagged as appropriate with one or more group memberships (and corresponding status). The group list section would also include a second list of all groups that are represented by the tagged entries in the general phone book listing, each entry in this second list corresponding to a group. A particular group can then be selected for monitoring by simply selecting the corresponding entry from the second list.
The group select input of FIGURE 3 is a user input that selects which group is to be monitored. Moreover, the group select input can designate the selected group as a closed user group so that the device 31 , while the closed user group designation
is active, communicates to and receives communication from only the group members in the selected group.
FIGURE 17 illustrates pictorially a wireless mobile communication device 170 according to the present invention. The bottom line of the display shows the status of the monitored units. Each character from left to right corresponds respectively to the status of one of the units of the group being monitored. For example, I = idle, B = busy, L = lunch, M = meeting, - = phone switched off. The user can dial another unit manually or check the status of another unit manually by using the arrow keys in the keyboard to select the position on the display that corresponds to the desired unit. A group can define its own status characters for use in the display.
The group update control section 33 and the group list section 35 of FIGURE 3 can be implemented within the unit 170 shown in FIGURE 17, or can alternatively be implemented in a device connected to the unit 170, for example the personal digital assistant PDA shown in broken lines in FIGURE 17. Also, as an alternative to the display shown in FIGURE 17, the status information can be presented using audible signals such as, for example, synthetic speech. The audible signals could be provided via a speaker 173 or an earphone.
Both of the aforementioned visible and audible status indications can be updated automatically whenever group list 35 is updated (see Figure 3). Although exemplary embodiments of the present invention have been described above in detail, this does not limit the scope of the invention, which can be practiced in a variety of embodiments.
